Abstract

L'invention concerne la transmission de données. Le dispositif de l'invention est destiné à acheminer sur une liaison commune 50 plusieurs trains élémentaires de données qui sont combinés en un train composite, puis séparés par des multiplexeurs/démultiplexeurs 28, 54. Le format des messages transmis réduit au minimum les informations qui doivent être transmises par la liaison pour déchiffrer correctement les données à la réception. Application aux réseaux de télé-informatique.The invention relates to data transmission. The device of the invention is intended to route on a common link 50 several elementary data streams which are combined into a composite stream, then separated by multiplexers / demultiplexers 28, 54. The format of the messages transmitted reduces the information which is transmitted to a minimum. must be transmitted over the link to correctly decrypt the data on reception. Application to tele-computing networks.
